House-sized asteroid discovered this week will fly past Earth on Friday
The near-Earth object, called 2023 EY, has been posted on NASA’s asteroid database and listed as one of the next five asteroid approaches. Scientists estimate it is about 54 feet wide.

NASA's Webb Telescope captures rarely seen star on cusp of death
The Webb Telescope saw gas and dust flung into space by a huge, hot star 15,000 light-years away. Such a transformation occurs only with some stars and normally is the last step before they explode, going supernova.

Time zone debate hits the moon; world asks what time is it really on the lunar body?
A joint international effort is underway to set a time zone on the moon. The natural satellite makes a complete orbit around Earth every 27 days, but the moon takes nearly 30 days to complete a full lunar day.
